A quasar, a force so destructive that it is capable of Destroy part of an entire galaxy. They are simply cosmic bodies so colossal that their energy released by the second, exceeds all the limits imaginable by the human being.
Quasars are as large as our solar system and have the ability to consume stars and planets very easily.
These ultra-bright cosmic bodies are probably the centers of active galaxies where supermassive black holes are housed. As the material spirals into black holes, much of the mass is converted into energy.
The "supermassive" black hole absorbs and crushes any material that comes close to it, including stars and entire planets. In the process, the material becomes infinitely hot and very bright, like a colorful disk. This disk, called the disk of accumulation, often covers an area almost the size of our solar system. It is what gives a quasar its luminous beauty.
Quasars can easily release energy at levels equal to the combination of hundreds of medium-sized galaxies. The light produced would be equivalent to nothing more than a billion suns. Almost nothing...
Quasars also shoot rays called "jets" that are composed of subatomic particles that move away from the quasar almost at the speed of light. If for example the earth received one of these rays, it would completely disintegrate in less than a flicker. There would not be the slightest particle, completely disintegrating.
Fortunately, no quasar is close to Earth. If so, we would all be dead. It would cook the surface of the Earth with massive bursts of radiation known as gamma rays. If it were close enough, the quasar could devour our planet, the Sun, the solar system, in a matter of months.
In fact it is estimated that 10 million years ago, there were 100 times more quasars in the universe than there are now.
The light that radiates a quasar takes many billions of light years to reach the earth, so what astronomers actually see are events that have already occurred many billions of years ago. In other words, the most certain thing is that these quasars, no longer exist.
Even so, very little is actually known about quasars.
From what there is no doubt, is that in the universe there are many fascinating events. So complex but so fascinating at the same time. Personally, the universe will never cease to amaze me, the mere fact of thinking that there are still many things to discover and understand up there, is very moving.
Who knows if maybe today when you look at the night sky you see a very radiant light spot, who knows if maybe at that moment you are seeing a majestic quasar or maybe something that has not yet been discovered. That's how amazing the universe is.
With nothing more to add, I say goodbye.
